I take a roll of duct tape and roll it around my hand sticky side out to pick up what the vac won't in the car. If you really want to get industrious you can unbolt most cars front seats in about 2 minutes, then you can get all of the build up by the console and under the seats.

Excuse me for being ignorant, but whats so bad about Nutro? I can never figure out what freakin food to feed the dogs...one group says one food is good and the other says that food is the devil...its frustrating. As far as I know, you want the first few ingredients to be meat, and then look for food with no corn, and then look for a small ingredient list. Oh yeah and no beat pulp...
